7. Perform the following:
. Clean the areas where the driveshaft(s) and theintermediate shaft contact the transmission (dif_ferential) thoroughly with solvent or carburetorcteaner, and dry with compressed air.. Check that the set rings on the ends of the drive_shaft and intermediate shaft click into place.CAUTION: Use new set rings,. Adjust the shift cable (see section 14).. Adjust the throttle cable (see section 11).. Adjust the cruise control cable (see section 23).. Refill the engine with engine oil (see page 8-6).. Refill the transmission with fluid (see section 13,14).
. Refill the radiator with engine coolant (see page10-7).
. Bleed air from the cooling system with the heatervalve open (see page j0-7).
. Clean the battery posts and cable terminals withsandpaper, assemble them, then apply grease toprevent corrosaon.. Inspect for fuel leakage (see section j l).After assembling the fuel line, turn on l) the igni_tion switch (do not operate the starter) so that thefuel pump runs for approximately two secondsand the fuel line pressurizes. Repeat this opera_taon two or three times, then check for fuel leak_age at any point in the fuel line,

How To Begin Troubleshooting
When the Malfunction Indicator Lamp (MlL) has been reported on, or there is a driveability problem, use the appropr'-
ate orocedure below to diagnose and repair the problem'
A. When the MIL has come on:
,1. connect the Honda PGM Tester or an oBD ll scan tool to the 16P Data Link connector (DLC) located near the left
kick panel.
2. Turn the ignition switch ON (ll)
3. Check the DTC and note it. Also check and note
the freeze trame data
Refer to the Diagnostic Trouble Code Chart and
begin troubleshooting.

Hydraulic Flow (cont'd)
2nd G.!r
As tha speed of the vehicle reaches the prescribed value, shift control solenoid valve A is turned oN by means of thePCM The modulator pressure {64} in the left end of the 1-2 shift valve is r€leased by turning shift controt sotenoidvalve A oN The 1-2 shift valve is moved to the left side and uncovers the port to allow line pressure {5) to the z-3shift valve. The line pressure (5) changes to the 2nd ctutch pfessure l2O) at the 2-3 shift valve. The 2nd clutch pressure(20) is applied to the 2nd clutch, and the 2nd clutch is engaged.
Fluid flows by way of:- Line Pressure (4) + cPB varve - Line pressure (s) * 'r-2 shift varve - Line pressure (5) * 2-3 shift varve- 2nd Clutch Pressure (20) + 2nd Clutch
The hydraulic pressure also flows to the 1st clutch. However, no power is transmittod because of the one-way ctutch.
NOTE: When used, "|eft" or ,,right,, indicates direction on the hydraulic circuit.

3. 3rd Gear
As the soeed of the vehicle reaches the prescribed value, shift control solenoid valve B is turned OFF by means ol the
pCM. Shift control solenoid valve A remains ON. The modulator pressure (6) flows to the right end of the 1-2 shift
valve and the left end oJ the 2-3 shift valve. The 2-3 shift valve is moved to the right side by the modulator pressure
(68). The 2-3 shift valve covers the port to stop line pressure (5) to the 2nd clutch and uncovers to the 3-4 shift valve
as the 2-3 shift valve is moved to the right side. The line pressure (5) becomes the 3rd clutch pressure (30) at the 3-4
shift valve. The 3rd clutch pressure (30) is applied to the 3rd clutch, and the 3rd clutch is engaged'
Fluid flows by way of:- Line Dressure (4) * CPB Valve - Line Pressure (5) * 1-2 Shift Valve - Line Pressure (5) * 2-3 Shift Valve
- Line Pressure (5) * 3-4 Shift Valve - 3rd Clutch Pressure (30) - 3rd Clutch
The hvdraulic pressure also flows to the 1st clutch. However, no power is transmitted because of the one-way clutch
as in 2nd gear.

4th Goar {E Position}
As the speed of the vehicle reaches the prescribed value, shift controlsolenoid valve A is turned OFF bymeans ofthePCM Shift control solenoid valve B remains oFF. The modulator pressure (6) flows to the left end of the t-2 shiftvalve and the left end of the 3-4 shift valve. The modulator pressure (64) in the left end of the 1-2 shift valve equalsthe modulator pressure {68) in the right end of the 1-2 shift valve, the 1-2 shift valve remains at left side by the ten-sion of the valve spring.
The 3-4 shift valve is moved to the right side by the modulator pressure (64). The 3_4 shift valve covers the port to the3rd clutch and uncovers the port to the 4th clutch as this valve is moved to the right side. The 4th clutch pressure (4.1)from the 3-4 shift valve becomes the 4th clutch pressure (40) at the manual valve. The 4th clutch pressure (401 isapplied to the 4th clutch, and the 4th clutch is engaged.
Fluid flows by way of:- Line pressure (4) * CPB Valve - Line Pressure (5) + 1-2 Shift Valve - Line pressure (5) * 2-3 Shift Valve- Line Pressure (5) - 3-4 Shift Valve - 4th Clutch pressure (41) + Manual Valve _ 4th Clutch pressure (40)* 4th Clutch
The hydraulic pressure also flows to the lst clutch. However, no power is transmitted because of the one-way crutchas in 2nd and 3rd gear.
NOTE: When used, "|eft" or "right,, indicates direction on the hydraulic circuit.

L
E Position
The flow of fluid through the torque convefter circuit is the same as in E position The line pressure (1) changes to the
line pressure (3) and flows to the l-2 shift valve. The iine pressure (3) changes to the line pressure (3') at the 'l-2 shift valve
and flows to the servo valve. The servo valve is moved to the right side (Reverse range position) and uncovers the port to
allow line pressure {3") to the manual valve, The line pressure {3') from the 1-2 shift valve flows through the servo valve to
the manual valve and changes the 4th clutch pressure (40). The 4th clutch pressure (40) is applied to the 4th clutch, and
the 4th clutch is engaged,
Reverse Inhibitor Control
When the E position is selected while the vehicle is moving forward at spe€ds over 6 mph (10 km/h)' the PCM outputs the
1st speed signal to shift control solenoid valves A and B; shift control solenoid valve A is turned oFF, shift control solenoid
valve B is turned ON. The 1-2 shift valve is moved to the right side and covers the port to stop line pressure (3') to the
servo valve. The line pressure (3') is not applied to the servo valve, and the 4th clutch pressure (40) is not applied to the
4th clutch, as a result, power is not transmitted to the reverse direction'
When used. 'left" or "right" indicates direction on the hydraulic circuit'
